6th CK HEAT AND ENERGY TRANSFER A - C SET 1 - COMPLETE
Term | Definition |
---|---|
Absolute zero | the temperature at which no more energy can be removed from matter. |
Amorphous Solid | the particles are not arranged in any particular order |
Biomass | Material in growing or dead plants. |
Boiling point | the temperature at which a liquid boils. |
Calorie | amount of heat required to raise the temperature of one gram of water one degree Celsius. |
Calorimeter | a device that measures changes in thermal energy |
Celsius scale | the temperature scale on which zero and 100 are the temperatures at which water freezes and boils. |
Change-of-state | a change from one state (solid or liquid or gas) to another without a change in chemical composition. |
Chemical Change | one or more substances break apart or combine to form a new substance |
Chemical Energy | potential energy stored in chemical bonds that hold chemical compounds together; for example, wood, wax, and food such as chocolate and broccoli store this |
Chernobyl | A place in Ukraine where a nuclear power plant – a generator powered by a nuclear reactor – underwent a meltdown in 1986. |
Combustion | Burning; a chemical reaction that involves the rapid combination of a fuel with oxygen to produce thermal energy. |
Condensation | the change from the gaseous to the liquid form of matter. |
Conduction | flow of heat energy from one molecule to the next; warmer particles passing some of their warmth onto cooler particles without the movement of matter itself. |
Conductor | a material that easily transfers heat between its particles. |
Contraction | when a substance loses heat energy, the molecules slow down, and the substance contracts to become smaller in size |
Convection | flow of energy/transfer of that that occurs when warm liquid or gas rises; particles move taking their heat with them |
Convection current | a current caused by the rising of heated fluid and sinking of cooled fluid. |
Crystalline Solid | the particles form regular, repeating patterns |
